Abstract (en)
[origin: EP1553678A1] The present invention approximates an induced voltage waveform to a sinusoidal waveform when the magnetic pole of a magnet opposing the respective teeth are switched while a rotor is rotating. <??>A plurality of magnetic poles 45a and 45b opposing a plurality of teeth 61 disposed substantially into a circular shape with the intermediary of a gap along the direction of revolving shaft BO, and being disposed substantially in circular shape, and a plurality of inter-pole sections 45c extending circumferentially from each of the adjacent magnetic poles out of the plurality of magnetic poles 45a and 45b and having tooth-opposed surfaces being set back with respect to the surfaces of the magnetic poles 45a and 45b opposing the teeth 61 in the direction of the revolving shaft BO are provided, and the plurality of magnetic poles 45a, 45b and the plurality of inter-pole sections 45c are integrally formed. <IMAGE>
